Stroke rehabilitation is associated with a reduction in dementia risk: A population-based retrospective cohort study.
Summary of "Stroke rehabilitation is associated with a reduction in dementia risk: A population-based retrospective cohort study."
Objective: Focusing on the relationship between physical activity and incident cognitive impairment, the aim of this study was to investigate whether stroke rehabilitation reduces the risk of dementia. Methods: Claims data of 1,000,000 insured subjects randomly selected from the National Health Insurance programme of Taiwan were used to identify adults with a newly diagnosed ischaemic stroke in 1997-2002. Among them, 1,375 received rehabilitation and 3,722 did not. Both groups were followed up until the end of 2007 to measure the incidence of development of dementia. Results: The incidence of development of dementia was lower in the rehabilitation cohort than in the non-rehabilitation cohort (1.22 vs 1.70 per 100 person-years), with an adjusted hazard ratio (HR) of 0.73 (95% confidence interval (CI) = 0.60-0.89) in the multivariate Cox proportional hazard regression analysis. Female gender (HR = 1.26, 95% CI = 1.07-1.50), older age (HR = 7.71, 95% CI = 3.36-17.7), low income (HR = 1.82, 95% CI = 1.42-2.33), and Parkinson's disease (HR = 1.64, 95% CI = 1.33-2.03) were risk factors associated with the development of dementia. Conclusion: Post-stroke rehabilitation is associated with a reduction in dementia risk among ischaemic stroke patients.

Risk Reduction Behavior
Reduction of high-risk choices and adoption of low-risk quantity and frequency alternatives.
The application of methods designed to reduce the risk of harm associated with certain behaviors without reduction in frequency of those behaviors. The risk-associated behaviors include ongoing and active addictive behaviors.
Ongoing scrutiny of a population (general population, study population, target population, etc.), generally using methods distinguished by their practicability, uniformity, and frequently their rapidity, rather than by complete accuracy.
The diagnosis and treatment of human responses of individuals and groups to actual or potential health problems with the characteristics of altered functional ability and altered life-style. (American Nurses Association & Association of Rehabilitation Nurses. Standards of Rehabilitation Nursing Practice, 1986, p.2)
Risk Sharing, Financial
Any system which allows payors to share some of the financial risk associated with a particular patient population with providers. Providers agree to adhere to fixed fee schedules in exchange for an increase in their payor base and a chance to benefit from cost containment measures. Common risk-sharing methods are prospective payment schedules (PROSPECTIVE PAYMENT SYSTEM), capitation (CAPITATION FEES), diagnosis-related fees (DIAGNOSIS-RELATED GROUPS), and pre-negotiated fees.
